    Trap flag when set then single step interrupt will occur after the next instruction.
    Are you sure? This action cannot be undone.

    #-Link-Snipped-# There is no specific instruction to set Trap flag. However, u can set it by changing the Trap Flag Bit of the flags register.
    Also, The Trap Flag is mainly used for debugging purposes.
    Hope it helps!!!

    More amazingly, this thread has thousands of views. It only goes to say engineers are searching for the basics and CE is providing them the answers. 👍

    So, here's my two cents:
    Trap Flag is used for on-chip debugging. Debuggers can use it for step-by-step execution of a computer program. If 8086 does a type-1 interrupt, Trap Flag is reset. Therefore, the single-step mode will be disabled during the interrupt-service procedure.
